Challenge
Germany is moving B2B invoicing to structured e-invoices: the invoice must be a structured file, not a PDF that looks like one. For a Polish-speaking business that means colliding with formats it never had to know about.
Solution
The app generates invoices in ZUGFeRD 2.3 and XRechnung 3.0 on the CII profile per EN16931, and stores documents in line with GoBD requirements. The interface is bilingual; outgoing documents are always German, formatted de-DE. The backend runs in europe-west3.
Status
The product runs commercially on its own domain. Alongside the web version, a Capacitor-based mobile build shares the same codebase.
